I guarantee you 95% of fans wouldn't be able to recognize said adjustments without the announcers telling it to them.
Iowa did adjust. It just so happened that Michigan did too, and hats off to them.
That would mean KF/BF got outcoached, which is pretty much the consensus. By defintion if you lose, you got out coached because coaches are paid recruit the right players, put in right system, make the right adjustments to win, play the right players.
I would agree that the threads that were blaming individual, not paid players were over the top. KF/BF are fair game.
